Septic Tanks Will Need to Be Inspected Before Buying or Selling a Home When you have a septic system attached to your home, you should take the time to have it inspected at least once every year. If nothing else, this will let you know what kind of condition your septic tank is in so that you can prepare for additional maintenance and repairs accordingly. You will also need to have a septic tank inspection done whenever you buy or sell a home. As a buyer, you never know how well a septic system has been maintained over the years, and the last thing you want to do is agree to purchase a home that has a septic system that needs to be replaced. It could cost you thousands of dollars and make your new home a nightmare. As a seller, you want to be able to use your septic system as a positive rather than a negative when selling your home. You should have it inspected so that you can let buyers know what a great job you’ve done pumping your septic tank and maintaining it. New septic tank installation isn’t something that buyers or sellers will want to think about, so a septic inspection will put everyone’s minds at ease during the selling process.
